A process that takes six transactions and a spreadsheet in SAP GUI can often become one Fiori screen designed around the person doing the work: a goods receipt at the dock, an inventory count in the aisle, a sales order at the desk, a material request that moves between departments. We build those applications on SAP Fiori and SAPUI5, with custom OData and Gateway services behind them and SAP authorizations underneath.
The result runs in the Fiori Launchpad on a desktop in the office, on a tablet in the warehouse and on a phone on the production floor, and it writes to the same SAP documents your business already relies on.
